What Researchers Did
Researchers compared cerebral SPECT and CT scans before and after hyperbaric oxygen treatment in 310 patients with neuropsychiatric disorders following traumatic brain injury.
What They Found
Before treatment, SPECT detected abnormal cerebral changes in 81.3% of patients, compared to only 15.2% by CT. Following hyperbaric oxygen treatment, 70.3% of SPECT scans showed no abnormalities, and these patients experienced clinical improvement and improved regional cerebral blood flow.
Canadian Relevance
This study has no direct Canadian connection as it was conducted in China and did not involve Canadian participants or institutions.
Study Limitations
A key limitation of this study is the absence of a control group, which makes it difficult to definitively attribute improvements solely to hyperbaric oxygen treatment.
